Thank you to those who replied off-list, for the helpful replies! The feedback basically ranged from neutral (maybe a little positive) to really negative. The main emphasis being on: use them only if you are redundant. Seems like things haven’t changed much since 2012. Thanks!

We are happy with them, but are looking for alternatives. At the location in question we need about 200M. Cogent recently contacted us, and I shied away a bit, based on this conversation a few years ago: http://mailman.nanog.org/pipermail/nanog/2012-May/048181.html Have opinions changed since then? Or is Cogent still the "budget alternative to have in your mix, but better to stay away from if you need high-performance, reliable, mostly standalone bandwidth" (which is how I would summarize the consensus in 2012)? Thanks, Adam

I have worked with two UK ISPs that have Cogent as one of their transit providers, neither have had any problems in the 5+ years they've both had the Cogent transit, it has always "just worked". Cheers, James.

And for the most part, that will be the case. If you're multi-homed, it's really not a major issue. It's more when someone is: 1. single-homed to Cogent and they get into a peering/transit/pay-us spat with one of the DFZ carriers, and Cogent gets de-peered. Single-homed customers of $de-peering_carrier disappear from your view of the Internet. 2. single-homed to one of said DFZ carriers and a peering/transit/pay-us spat arises with Cogent, and Cogent gets de-peered. Single-homed customers of Cogent's disappear from your view of the Internet. jms
There is also the problem with multi-homed customers where Cogent is in the mix. The dropped packets at Cogent's peering points to eyeball networks break certain protocols that are packet loss sensitive (VoIP, IPSEC, etc...). ---- Matthew Huff | 1 Manhattanville Rd Director of Operations | Purchase, NY 10577 OTA Management LLC | Phone: 914-460-4039 aim: matthewbhuff | Fax: 914-694-5669 -----Original Message----- From: NANOG [mailto:nanog-bounces@nanog.org] On Behalf Of Justin M.
